In the following description, there are cases in which the buttons 3A to 3F are referred to collectively as a “button 3” without specifying a certain button.

The touch screen display 2 includes a display 2A and a touch screen 2B. The display 2A is equipped with a display device such as a liquid crystal display (LCD), an organic electro-luminescence (EL) panel, or an inorganic EL panel. The display 2A displays a text, an image, a symbol, or a diagram.

The touch screen 2B detects, for example, a contact of a finger, a pen, or a stylus pen with the touch screen 2B. The touch screen 2B can detect a position at which a plurality of fingers, pens, stylus pens, or the like contacts with the touch screen 2B.

A detection method of the touch screen 2B may be an arbitrary method such as a capacitive method, a resistive method, a surface acoustic wave (SAW) (an ultrasonic method), an infrared method, an electromagnetic induction method, or a load detection method. Hereinafter, in order to simplify a description, there are cases in which a finger, a pen, a stylus pen, and the like whose contact is detected through the touch screen 2B are referred to simply as a “finger.”

The smartphone 1 determines a type of gesture based on at least one of a contact detected by the touch screen 2B, a position at which a contact is detected, an interval at which a contact is detected, and the number of contact detections. A gesture is an operation performed on the touch screen 2B. Examples of the gesture determined by the smartphone 1 include, but are not limited to, a touch, a long touch, a release, a swipe, a tap, a double tap, a long tap, a drag, a flick, a pinch-in, and a pinch-out.

The “touch” is a gesture in which the finger touches the touch screen 2B. The smartphone 1 determines a gesture in which the finger contacts with the touch screen 2B as the touch. The smartphone 1 determines a gesture in which a single finger contacts with the touch screen 2B as a single touch. The smartphone 1 determines a gesture in which a plurality of fingers contacts with the touch screen 2B as a multi-touch. The smartphone 1 detects the number of fingers whose contact is detected in the case of multi-touch. The “long touch” is a gesture in which the finger touches the touch screen 2B during a predetermined period of time or more. The smartphone 1 determines a gesture in which the finger contacts with the touch screen 2B during a predetermined period of time or more as the long touch.

The “release” is a gesture in which the finger is separated from the touch screen 2B. The smartphone 1 determines a gesture in which the finger is separated from the touch screen 2B as the release. The “swipe” is a gesture in which the finger moves while contacting with the touch screen 2B. The smartphone 1 determines a gesture in which the finger moves while contacting with the touch screen 2B as the swipe.

The “tap” is a gesture that the release is performed subsequently to the touch. The smartphone 1 determines a gesture in which the release is performed subsequently to the touch as the tap. The “double tap” is a gesture in which the gesture in which the release is performed subsequently to the touch is consecutively performed twice. The smartphone 1 determines a gesture in which the gesture in which the release is performed subsequently to the touch is consecutively performed twice as the double tap.

The “long tap” is a gesture in which the release is performed subsequently to the long touch. The smartphone 1 determines a gesture in which the release is performed subsequently to the long touch as the long tap. The “drag” is a gesture in which the swipe is performed starting from a region on which a movable object is being displayed. The smartphone 1 determines a gesture in which the swipe is performed starting from a region on which a movable object is being displayed as the drag.

The “flick” is a gesture in which the release is performed while moving the finger in one direction subsequently to the touch. The smartphone 1 determines a gesture in which the release is performed while moving the finger in one direction subsequently to the touch as the flick. A moving speed of the flick is faster than moving speeds of the swipe and the drag. Examples of the flick include, but are not limited to, an “upper flick” in which the finger moves in an upward direction of the screen, a “lower flick” in which the finger moves in a downward direction of the screen, a “right flick” in which the finger moves in a right direction of the screen, a “left flick” in which the finger moves in a left direction of the screen, an “oblique upper left flick” in which the finger moves in an oblique upper left direction of the screen, an “oblique lower left flick” in which the finger moves in an oblique lower left direction of the screen, an “oblique upper right flick” in which the finger moves in an oblique upper right direction of the screen, and an “oblique lower right flick” in which the finger moves in an oblique lower right direction of the screen.

The “pinch-in” is a gesture in which a plurality of fingers swipe in an approaching direction. The smartphone 1 determines a gesture in which a plurality of fingers swipe in an approaching direction as the pinch-in. The “pinch-out” is a gesture in which a plurality of fingers swipe in a separating direction. The smartphone 1 determines a gesture in which a plurality of fingers swipe in a separating direction as the pinch-out.

The smartphone 1 performs the operation according to the gesture determined through the touch screen 2B. Thus, operability in which the user can use the smartphone 1 intuitively and easily is implemented. An operation performed according to a determined gesture by the smartphone 1 differs according to a screen displayed on the display 2A. Hereinafter, in order to simplify a description, there are cases in which an expression “the smartphone 1 detects X” or “a controller detects X” is used to mean an expression “the touch screen 2B detects a contact, and the smartphone 1 determines a type of gesture to be X based on the detected contact.”

An exemplary screen displayed on the display 2A will be described with reference to FIG. 4. FIG. 4 illustrates an exemplary home screen. The home screen is also referred to as a “desktop” or an “idle screen.” The home screen is displayed on the display 2A. The home screen is a screen in which the user selects an application to be executed among applications installed in the smartphone 1. The smartphone 1 executes an application selected on the home screen on the foreground. A screen of the application executed on the foreground is displayed on the display 2A.

In the smartphone 1, an icon may be arranged on the home screen. A plurality of icons 50 are arranged on a home screen 40 illustrated in FIG. 4. Each of the icons 50 is associated with an application installed in the smartphone 1 in advance. Upon detecting the gesture on the icon 50, the smartphone 1 executes the application associated with the icon 50. For example, upon detecting the tap on the icon 50 associated with a mail application, the smartphone 1 executes the mail application.

The icon 50 includes an image and a character string. The icon 50 may include a symbol or a diagram instead of an image. The icon 50 may include neither an image nor a character string. The icons 50 may be arranged based on an arrangement pattern. Wallpaper 41 is displayed on the back of the icon 50. The wallpaper is also called a photo screen or a back screen. The smartphone 1 can use an arbitrary image as the wallpaper 41. An arbitrary image may be decided as the wallpaper 41 according to a setting performed by the user.

The smartphone 1 may increase the number of home screens 40. For example, the smartphone 1 may decide the number of home screens 40 according to a setting performed by the user. When there is a plurality of home screens 40, the smartphone 1 causes a selected home screen to be displayed on the display 2A.

The smartphone 1 displays a locator 51 including one or more symbols on the home screen 40. The number of symbols is equal to the number of home screens 40. The locator 51 indicates the home screen 40 that is currently being displayed. In the locator 51, a symbol corresponding to the home screen 40 that is currently being displayed is displayed in a different from the other symbols.

In an example illustrated in FIG. 4, the locator 51 including three symbols is displayed. This indicates that the number of home screens 40 is 3. Each of the three symbols has a circular shape. In an example illustrated in FIG. 4, a symbol at the left end is displayed in a different form from the other symbols. In other words, the symbols except the symbol at the left end are displayed as a circular rim, but the symbol at the left end is displayed in a form in which the inside of the circular rim is filled. This indicates that the home screen 40 at the left end is currently being displayed on the display 2A.

Upon detecting a gesture in a crosswise direction while the home screen 40 is being displayed, the smartphone 1 switches the home screen 40 displayed on the display 2A according to the gesture. For example, upon detecting the right flick, the smartphone 1 switches the home screen 40 displayed on the display 2A to the next home screen 40 on the left. For example, upon detecting the left flick, the smartphone 1 switches the home screen 40 displayed on the display 2A to the next home screen 40 on the right. A process in which the smartphone 1 switches the home screen 40 in the crosswise direction according to the flick gesture in the crosswise direction will be described in detail later. When the home screen 40 is switched in the crosswise direction, the smartphone 1 updates a display of the locator 51 according to the position of the switched home screen 40.

A region 42 is disposed on the top of the display 2A. A remaining level mark 43 indicating a remaining battery level and a radio level mark 44 indicating field strength of a radio wave for communication are displayed on the region 42. The smartphone 1 may display a time, weather, an application being executed, a type of communication system, a phone call status, a device mode, an event occurring in a device, or the like on the region 42. As described above, the region 42 are used to given various kinds of notifications to the user. The region 42 may disposed on a screen other than the home screen 40. The position at which the region 42 is disposed is not limited to the top of the display 2A.

A vertical direction of the home screen 40 is a direction based on a vertical direction of a text or an image displayed on the display 2A. Thus, a side of the home screen 40 close to the region 42 in a longitudinal direction of the touch screen display 2 is an upper side of the home screen 40, and a side of the home screen 40 far from the region 42 is a lower side of the home screen 40. A side of the region 42 at which the radio level mark 44 is displayed is a right side of the home screen 40, and a side of the region 42 at which the remaining level mark 43 is displayed is a left side of the home screen 40. The smartphone 1 decides, for example, the oblique upper left direction, the oblique lower right direction, the left direction, and the right direction of the home screen 40 based on the vertical direction of the text or the image displayed on the home screen 40.

The home screen 40 illustrated in FIG. 4 is an example, and forms of various kinds of elements, an arrangement of various kinds of elements, the number of home screens 40, and various kinds of operation methods on the home screen 40 may be different from those described above.

In an example illustrated in FIG. 5, the smartphone 1 is equipped with two cameras, but the smartphone 1 may be equipped with one camera or may be equipped with no camera. In an example illustrated in FIG. 5, the smartphone 1 is equipped with the three types of sensors for detecting a position and an attitude, but the smartphone 1 may not be equipped with some of the sensors. Alternatively, the smartphone 1 may be equipped with any other type of sensor for detecting at least one of a position and an attitude.

A process performed by the smartphone 1 according to the gesture of the user on the touch screen display 2 will be described below with reference to FIGS. 6 to 13.

FIG. 6 is a view illustrating a first example of control performed by a smartphone according to an embodiment. In FIG. 6, the user moves the finger in the right direction in a state in which the finger contacts to a predetermined region nearby the left end of the home screen 40. Or, the user is tracing the surface of the touch screen display 2. At this time, the controller 10 of the smartphone 1 detects the swipe. Specifically, the controller 10 detects the swipe performed in the right direction starting from the inside of the predetermined region near by the left end of the home screen 40. Then, when the user moves the finger in the right direction, the controller 10 causes a memo object 55 to be displayed on the home screen 40 according to the trajectory of the moving. The memo object 55 is an object having a tag shape. The memo object 55 is displayed as if a portion thereof positioned at the left end side of the home screen 40 serving as the starting point of the swipe is attached to the home screen 40. The memo object 55 is displayed corresponding to a region traced by the user.

The predetermined region nearby the left end of the home screen 40 is, for example, a region between the left end of the home screen 40 and a position that is away from the left end of the home screen 40 by a length of one twentieth ( 1/20) of the length of the home screen 40 in the lateral direction. A position and an area size of the predetermined region can be appropriately set. For example, the predetermined region may be a region nearby any one of the right end, the lower end, or the upper end of the home screen 40.

When the memo object 55 is displayed on the home screen 40, the controller 10 may display the memo object 55 such that the memo object 55 gradually increases in length (gradually extends) while following the finger of the user while the swipe is being performed. The controller 10 may not display the memo object 55 while the swipe is being performed, and instead, when the swipe ends, that is, when the finger of the user is detected to have been separated from the touch screen 2B, the controller 10 may display the memo object 55 initially at that point in time. The controller 10 may set the length of the memo object 55 to be equal to the length of the trajectory of the swipe or may set the length of the memo object 55 to be smaller or larger than the length of the trajectory of the swipe.

FIG. 7 is a flowchart illustrating a processing procedure of a first example of the control performed by a smartphone according to an embodiment.

At step S1, the controller 10 of the smartphone 1 detects the swipe. Subsequently, the controller 10 proceeds to step S2. At step S2, the controller 10 determines whether or not the starting point of the detected swipe is within the region at the end of the home screen 40. In an example illustrated in FIG. 6, the region at the end of the home screen 40 is the region between the left end of the home screen 40 and the position away from the left end of the home screen 40 by a length of one twentieth ( 1/20) of the length of the home screen 40 in the lateral direction. When the starting point of the detected swipe is determined to be within the region at the end of the home screen 40 (Yes at step S2), the controller 10 proceeds to step S3. When the starting point of the detected swipe is determined to be not within the region at the end of the home screen 40 (No at step S2), the controller 10 proceeds to step S4.

At step S3, the controller 10 causes the memo object 55 to be displayed along the trajectory of the swipe on the home screen 40. At step S4, the controller 10 changes the home screen 40 to another home screen.

Then, a process of inputting a text onto the memo object 55 will be described with reference to FIG. 8. FIG. 8 is a view illustrating a process of inputting a text onto the memo object. When the memo object 55 is displayed through the process illustrated in FIG. 6, the controller 10 of the smartphone 1 displays a text input screen illustrated at step S11 of FIG. 8 so that a text can be input onto the memo object 55. The text input screen includes a text input region 60 and a keyboard 61. At step S11 of FIG. 8, an example in which the user inputs a character string “14:00 Shibuya” onto the text input region 60 is illustrated.

Upon detecting the tap on the memo object 55 after the memo object 55 is displayed, the controller 10 may transition to the text input screen. The controller 10 may automatically transition to the text input screen while displaying the memo object 55 when the swipe ends, that is, when the finger of the user is detected to have been separated from the touch screen 2B.

When an input of the text is decided, a degree of importance of the memo object 55 may be set as illustrated at step S12 of FIG. 8. Of course, transition to a screen in which a degree of importance is set may not be performed.

Then, when the input of the text is decided based on the operation of the user, and when a degree of importance of the memo object 55 is set, the controller 10 causes the memo object 55 to be displayed on the home screen 40 at step S13 of FIG. 8. The text input to the text input region 60 at step S11 of FIG. 8 is displayed on the memo object 55. At step S13 of FIG. 8, the memo object 55 is displayed to overlap some of a plurality of icons 50 displayed on the home screen 40.

FIGS. 9A and 9B are views illustrating a second example of control performed by a smartphone according to an embodiment. The icon 50 corresponding to the memo application is displayed on the home screen 40 as illustrated in FIG. 9A. Further, the user moves the finger in the right direction in a state in which the finger contacts to the icon 50. At this time, the controller 10 of the smartphone 1 detects the swipe in the right direction starting from the icon 50. Then, when the user moves the finger in the right direction, the controller 10 causes the memo object 55 to be displayed on the home screen 40 in the crosswise direction along the trajectory of the moving. In FIG. 9A, the memo object 55 is displayed to be drawn from the icon 50.

FIG. 9A illustrates an example in which the user performs the swipe in the right direction from the icon 50 corresponding to the memo application, but the direction of the swipe is not limited thereto. In FIG. 9B, the user performs the swipe in the downward direction from the icon 50. Upon detecting the swipe in the downward direction starting from the icon 50, the controller 10 causes the memo object 55 that is long in the vertical direction to be displayed on the home screen 40 along the trajectory of the swipe.

The controller 10 may decide whether the text can be written on the memo object 55 vertically or horizontally according to the direction of the swipe. In other words, when the horizontally long memo object 55 is displayed as illustrated in FIG. 9A, the text may be written horizontally on the text input region 60 of step S11 of FIG. 8, whereas when the vertically long memo object 55 is displayed as illustrated in FIG. 9B, the text may be written vertically on the text input region 60.

FIG. 10 is a view illustrating a third example of control performed by a smartphone according to an embodiment. At step S21 of FIG. 10, the user performs the swipe in the left direction on a home screen 40 a on which a memo object 55 a is displayed. The starting point of the swipe is nearby the center of the home screen 40 a rather than the inside of the predetermined region at the end of the home screen 40 a. The controller 10 determines that the starting point of the detected swipe is not the inside of the region at the end of the home screen 40 a as illustrated in the flowchart of FIG. 7, and changes the home screen 40 a to a home screen 40 b that is a home screen on the right of the home screen 40 a as illustrated at step S22 of FIG. 10. At this time, the controller 10 causes a different memo object 55 b from the memo object 55 a that is originally displayed to be displayed on the home screen 40 b.

As described above, the controller 10 associates the memo object 55 a with the home screen 40 a, and causes the associated memo object 55 b to be displayed on the home screen 40 b displayed on the display 2A when the gesture for changing (or switching) the home screen 40 a is performed. The controller 10 may cause the memo object 55 a to be displayed on the home screen 40 b, for example, when the gesture of changing (or switching) the home screen 40 a is performed in the state in which the tap on the memo object 55 a is detected. In other words, the controller 10 may change the home screen in a state in which the memo object 55 a is displayed.

FIGS. 11A and 11B are views illustrating a fourth example of control performed by a smartphone according to an embodiment. In FIG. 11A, when the memo object 55 is being displayed on the home screen 40, the user performs the swipe on the region 42 in the downward direction. Upon detecting the swipe on the region 42, the controller 10 displays a drawer 420 while following the swipe. The drawer 420 is a region on which various information such as information indicating that there is a non-read mail and information indicating that an application has been updated. As illustrated in FIG. 11A, the controller 10 causes the memo object 55 to be covered with the drawer 420 drawn from the region 42 according to the swipe of the user, and thereafter causes the memo object 55 to disappear when the user performs the swipe on the drawer 420 in a direction (a direction for returning the drawn drawer 420 to the region 42) facing the region 42. As a result, visibility of the home screen 40 is secured.

After the memo object 55 disappears, when the user causes the drawer 420 to be displayed again and then performs the gesture for returning the drawer 420, the memo object 55 is displayed on the home screen 40 again as illustrated in FIG. 11B.

FIG. 12 is a view illustrating a fifth example of control performed by a smartphone according to an embodiment. At step S31 of FIG. 12, the user performs the flick on the memo object 55 displayed on the home screen 40 in the left direction. Upon detecting the flick performed on the memo object 55 in the left direction, the controller 10 causes the memo object 55 to be displayed on the home screen 40 so that a part of the memo object 55 extended from the end of the home screen 40 as illustrated at step S32 of FIG. 12. At step S31 of FIG. 12, for example, when “14:00 Shibuya” is input on the memo object 55 as illustrated at step S13 of FIG. 8, “Shibu 14” may be displayed on a part of the memo object 55 positioned at the end of the home screen 40 in the state illustrated at step S32 of FIG. 12. In other words, when the memo object 55 on which a predetermined character string is input transitions to the state in which only a part thereof is displayed, the controller 10 may cause a part of the input character string to be displayed on the part of the memory object. As a result, the user can check the presence of the memo object while checking the visibility of the home screen 40, and thus the usability is improved.

FIG. 13 is a view illustrating a sixth example of control performed by a smartphone according to an embodiment. In FIG. 13, a lock screen 45 is displayed on the display 2A. The lock screen 45 is a screen disposed to prevent unauthorized use of the smartphone 1. The user performs the swipe on the lock screen 45 as illustrated in FIG. 13. Upon detecting the swipe, the controller 10 causes the memo object 55 to be displayed on the lock screen 45 along the trajectory of the swipe.

Since the smartphone 1 can switch and display a plurality of home screens 40 as described above with reference to FIG. 10, the controller 10 can distinguish the swipe for switching the home screen 40 from the swipe for displaying the memo object 55 according to the flowchart illustrated in FIG. 7. However, since the lock screen 45 does not include a screen of a target switched by the swipe, the memo object 55 may be displayed even when the starting point of the swipe is the center of the lock screen in the state in which the lock screen 45 is displayed as illustrated in FIG. 13. In other words, the starting point of the swipe may not be a region at the end of the screen.

Further, when the tap on the memo object 55 is detected in the state in which the memo object 55 is displayed on the lock screen 45, and an unlocking operation is detected to have been performed, the controller 10 may cause the memo object 55 displayed on the lock screen 45 to be displayed on the home screen 40.

As described above, when the swipe on the home screen 40 or the lock screen 45 is performed, the smartphone 1 according to an embodiment displays the memo object 55 on which a text can be input along the trajectory of the swipe. Thus, it is possible to cause a memo object on which information is displayable to be displayed on the home screen through an intuitive operation without activating a specific application, and thus usability is improved. The control of the smartphone 1 according to an embodiment illustrated in FIG. 6 is smaller in the number of processes for arranging the memo object on the home screen than a technique of tapping an icon arranged on the home screen, activating the memo application, and then arranging the memo object on the home screen through a predetermined operation, and thus the usability of the user is improved.

According to the control illustrated in FIG. 9, it is possible to generate the memo object starting from the memo application icon arranged on the home screen 40, and thus the user can easily arrange the memo object on the screen through the intuitive operation.

The smartphone 1 according to an embodiment is not limited to the above-described control examples, and various embodiments are considered. For example, in above examples, information related to a time such as “14:00 Shibuya” is input onto the memo object 55. The controller 10 of the smartphone 1 may cause the memo object 55 on which a time has been input to disappear when the input time elapses as described above. Alternatively, when an input time elapses, the memo object 55 may be display in a form in which the memo object 55 is peeled off from the screen, a form in which a color is dull, a form in which there is a crack, or a form in which it is folded. Thus, when the user inputs his/her schedule on the memo object 55, the user can be notified of that a schedule time has elapsed such that a display form of the memo object 55 in which a schedule time has elapsed is changed as described above. As a result, the user who has been notified of can delete, for example, the memo object 55 in which the time has elapsed.

Further, when the same or similar information as or to information input onto a plurality of memo objects 55 is input, the controller 10 may cause the plurality of memo objects 55 to overlap at least a part of both pieces of information. Thus, the visibility of the home screen can be secured.

Further, when the taps performed at two different points on the home screen 40 or the lock screen 45 are detected, the controller 10 may display the memo object 55. At this time, the length of the memo object 55 may be equal to a distance between the two points at which the tap is detected.

Further, when the swipe in the opposite direction to the swipe for generating the memo object 55 is performed on the memo object 55 as illustrated in FIG. 12, the controller 10 may delete the memo object 55.
